SWF XRGB (swf_xrgb)

struct swf_xrgb {
	unsigned char		f_pad;
	unsigned char		f_red;
	unsigned char		f_green;
	unsigned char		f_blue;
};

Images without an alpha channel which are saved using 32 bits (format 5) use XRGB colors.

The f_pad field should be set to zero or 255.

The color components can be set to any value from 0 (no intensity) to maximum intensity (255).
